Bug Description

Keyboard navigation for the flow view is currently broken

When a user moves the focus down to the flow view the far left icon should become focused, with the white highlight we use to designate that an item is focused in the Dash. The behaviour of how the flow moves using focus should be identical to the interactions used in Ubuntu TV, e.g. there should not be any movement when the focus in the middle group of icons, and the flow view should start to move when the focus reaches the left or right of the visible area. Review the Ubuntu TV interface for details of exactly how this should work.

The App Lens and the 'Apps Available for Download' category header was used to test the above.
